摘要
传统冲击电压发生装置采用塔式开放型结构,其体积和重量非常庞大,需拆装分级运输,现场试验时需专业人员配合,实施难度较大。为此,采用封闭式气体绝缘结构完成了3 000 kV/300 k J紧凑型一体式冲击电压发生器的设计研究,包括电阻、点火球隙等内部器件的优化设计、装置本体电场仿真计算分析等,整体本体的尺寸降低约37%,重量降低约25%。同时,该装置采用卧式运输、立式使用方案,无需现场拼装,极大地提高了现场工作效率。研制的气体绝缘冲击电压发生装置依照国家标准进行了各项性能测试,均满足要求,能够有效解决超、特高压GIS等变电设备现场试验困难的问题。
The traditional impulse voltage generating device is of open-type tower structure, possessing huge volume and weight. So disassembly is needed for transport, and the field test is a rather complicated work and needs many professionals. In this study, the a 3 000 kV/300 kJ compact integrated impulse voltage generator with closed gas insulation structure was designed, including the optimization design of internal devices such as resistance and ignition ball gap, and the electric field simulation of the main body. The whole body size of the generator is reduced by about 37% and the weight is reduced by about 25%, compared with the traditional device. This generator takes the scheme of horizontal for transport and vertical for work without on-site assembly, greatly improving the field working efficiency. This gas-insulated impulse voltage generator was tested in accordance with national standards, its performance indexes met the requirements, and it can effectively solve difficult on-site test problems for ultra-high voltage GIS and other substation equipment.
